These are captive, wing bolts for replacing the threaded OEM fasteners on the PT300 track frames. The OEM bolts are prone to loosening and shearing off. Ream the OEM threaded holes to 5/8" diameter and install these bolts. They use a nyloc nut to provide consistent clamping force. If they do shear off, they are easily knocked out and replaced, reducing downtime and hours of fighting broken bolts.
60 positions are available in the track frame for these through bolts on a PT300. The remaining positions have internal ribbing which blocks the use of these bolts.
Sold individually. Select from fully assembled, loose pieces, or just the wings to add to your own hardware.
